AWS Lambda's support for Rust has moved from Experimental to Generally Available, making it suitable for business-critical serverless applications. Rust offers performance comparable to C++ with the reliability of higher-level languages. The third-party open-source tool Cargo Lambda simplifies building and deploying Rust Lambda functions and includes a CDK construct.

Red Hat OpenShift 4.20 introduces enhanced security, AI acceleration, and expanded virtualization to unify enterprise IT across hybrid and sovereign cloud environments. The release strengthens encryption with post-quantum cryptography, improves identity and secret management, and adds AI orchestration, faster model deployment, and optimized virtualization for both containers and virtual machines.

GitHub Copilot CLI lets users interact with Copilot directly from the terminal to generate scripts, refactor code, run commands, and get explanations without leaving their workflow. It supports interactive and programmatic modes, integrates with MCP servers for custom capabilities, and helps automate tasks, maintain codebases, generate documentation, and prototype projects efficiently.

Cloudflare reduced configuration management failures by over 5% through a new infrastructure that helps find the root cause of Salt failures on servers. The new system correlates failures with git commits, external service failures, and ad hoc releases, which has reduced software release delays and toil for SRE. A custom Salt execution module called "Salt Blame" pulls local job history, CM inputs, and GitHub repo commit history together.

Snap's Valdi, a cross-platform UI framework used in its production apps for 8 years, has been released in beta. The framework compiles declarative TypeScript components into platform-native views for iOS, Android, and macOS, avoiding web views and JavaScript bridges to improve performance.

Token-Oriented Object Notation (TOON) is a compact and human-readable JSON alternative that minimizes tokens for LLM prompts by combining YAML's indentation with CSV-style tabular arrays. Benchmarks reveal that TOON achieves 73.9% accuracy, outperforming JSON's 69.7%, while using 39.6% fewer tokens. A TypeScript SDK is available, and community tools have been created for token comparison, format conversion, and validation.

Microsoft and Anyscale announced a partnership to bring Anyscale's managed Ray service to Azure as a native offering in private preview, combining Ray's open-source distributed computing with Azure's enterprise infrastructure. The integration enables developers to scale Python-based AI and ML workloads efficiently using Anyscale Runtime on Azure Kubernetes Service with unified governance, security, and scalability.

Datadog Storage Management helps organizations reduce Amazon S3 costs by providing prefix-level visibility into which teams, services, and datasets drive storage use. It identifies cold data, recommends cost-saving actions such as transitioning to cheaper tiers or consolidating small files, and integrates with workflow tools to streamline optimization decisions.

A Chinese state-sponsored group manipulated the Claude Code AI tool in mid-September 2025 to infiltrate roughly 30 global targets, marking what is believed to be the first documented case of a large-scale cyberattack executed without substantial human intervention. The AI was used to perform 80-90% of the campaign, analyzing target systems, producing exploit code, and scanning stolen data at speeds impossible for human hackers. It is advised that security teams should experiment with applying AI for defense, as this attack demonstrates how threat actors are adapting their operations to exploit today's most advanced AI capabilities.

According to the latest DORA Report, 90% of developers now use AI as part of their work. How does this impact productivity metrics, platforms and culture? Explore engineering perspectives by Thoughtworks

Ten key techniques for improving Python performance.

Real-time machine learning, where apps autonomously make decisions impacting businesses in real-time, is becoming more accessible.

Combining Azure Load Balancer with Virtual Machine Scale Sets enhances both security and high availability in Azure environments.
